今(jin)日（4月(yue)20日）起，燃(ran)煤發電(dian)(dian)上網(wang)電(dian)(dian)價和工(gong)商業用(yong)電(dian)(dian)價格開始下調，全國(guo)燃(ran)煤發電(dian)(dian)上網(wang)電(dian)(dian)價平均每千(qian)瓦(wa)時下調約2分錢（含(han)稅(shui)(shui)），全國(guo)工(gong)商業用(yong)電(dian)(dian)價格平均每千(qian)瓦(wa)時下調約1.8分錢（含(han)稅(shui)(shui)）。

　　發(fa)改委稱，下調(diao)燃煤發(fa)電(dian)(dian)上網電(dian)(dian)價(jia)形(xing)成的降價(jia)空間，除適當(dang)疏導部分地區(qu)天然(ran)氣(qi)發(fa)電(dian)(dian)價(jia)格以(yi)及脫硝、除塵、超低(di)排(pai)放環保電(dian)(dian)價(jia)等突出(chu)結構性矛(mao)盾，促進節能減排(pai)和大氣(qi)污染(ran)防(fang)治外，主要用(yong)于(yu)下調(diao)工商業用(yong)電(dian)(dian)價(jia)格。

　　但就電(dian)(dian)(dian)解(jie)鋁(lv)(lv)行業(ye)來說，有業(ye)內人士表示，電(dian)(dian)(dian)解(jie)鋁(lv)(lv)的生產(chan)成本中，40%左右(you)來自(zi)電(dian)(dian)(dian)價(jia)，但目前國內鋁(lv)(lv)企業(ye)的自(zi)備電(dian)(dian)(dian)廠(chang)(chang)(chang)比例(li)已經(jing)很(hen)高(gao)，用網電(dian)(dian)(dian)的電(dian)(dian)(dian)解(jie)鋁(lv)(lv)廠(chang)(chang)(chang)很(hen)少，下調電(dian)(dian)(dian)價(jia)對鋁(lv)(lv)價(jia)影響有限，除此之外，很(hen)多電(dian)(dian)(dian)解(jie)鋁(lv)(lv)廠(chang)(chang)(chang)跟電(dian)(dian)(dian)廠(chang)(chang)(chang)簽了直購電(dian)(dian)(dian)協議，電(dian)(dian)(dian)價(jia)下調對電(dian)(dian)(dian)解(jie)鋁(lv)(lv)的意(yi)義不(bu)是那么(me)大了。
